If the dough is too dry, add a little more water, if it is too moist add a little more flour. Remove the dough from the bowl and continue kneading vigorously with your hands for 8-10 minutes. Wrap in foil and let it rest at room temperature for about 1 hour
Crumble the gorgonzola, mix with 200 g ricotta and season with pepper. Roll out the pasta dough thinly in portions with the pasta machine (up to level 6) on a floured work surface.
